Description
- The present invention refers to a device for cleaning vehicle surfaces such as headlamps. Windshield and headlamp cleaning devices are generally known in the art. Nowadays the cleaning devices are designed such that the surface to be cleaned is only cleaned by a jet of cleaning fluid which is discharged under pressure from one or more spray nozzles. The jet of cleaning fluid discharged from the spray nozzles is sufficiently energized to ensure a proper cleaning action No additional mechanically operating cleaning means as wipers or the like are required to achieve a satisfying cleaning result.
- Cleaning devices which are arranged in concealed fashion normally use the pressure of the cleaning fluid for extension movement of the nozzles which sometimes are fixed on a telescoping cylinder arrangement which is held in a retracted position by means of a return spring. Said cylinder arrangement can be hydraulically activated by the way of the pressure of the cleaning fluid, in which case firstly the pressure of the return spring acting on the cylinder has to be overcome upon extension of the spray nozzle by way of the pressure of the cleaning fluid.
- Conventional designs of telescopic headlamp cleaning devices which use the pressure of the cleaning fluid for the extension movement of the nozzles require fluid valves establishing fluid communication with the spray nozzle once the nozzles are in the fully extended position. Such designs of headlamp cleaning devices known in the art for this purpose utilize spring biased non-return valves operated by the fluid pressure.
- Accordingly cleaning devices utilizing so-called "pop-up nozzles" are expensive due to the number of moving parts required for controlling the extension movement of the nozzles.
- However, also nozzle arrangements which are not hidden from external view sometimes require return valves, for instance when several nozzles are to be arranged in series and/or in parallel.
- A headlamp cleaning device according to the preamble of claim 1 is for instance disclosed in
US patent application No. 2004/0188541 A1 . This reference discloses a valve arrangement which is arranged in a fluid passage of a nozzle body of a washer nozzle. The valve arrangement permits forward flow of the washer fluid in a first direction from an inlet opening of the nozzle body towards discharge opening of the nozzle body and blocks back-flow of the washer fluid in a second direction opposite from the first direction. Back-flow is prevented by a check valve including a disc-shaped valve body which is biased in the closed position by a compression coil spring. However, the reference teaches that the compression coil spring can be eliminated to construct the check valve unit only with the valve arrangement if the required closing force can be achieved only by the urging force of an anchoring portion and the connectors of the valve arrangement. - Another check valve of a cleaning device of a vehicle lamp is disclosed in
US patent application No. 2006/0114666 A1 . - It is therefore an object of the present invention to provide a device for cleaning vehicle surfaces, particularly a headlamp cleaning device which is simple to manufacture and cost-effective.
- It is furthermore an object of the present invention to provide a device for cleaning vehicle surfaces which has a reduced number of moving parts.
- These and other objects are achieved by a device as defined by claim 1.
- Springless in the sense of the present application means that the valve is designed such that an additional spring member, for instance a return spring as a coil spring, is not required anymore. Opening of the valve according to the invention is only achieved by positive fluid pressure being applied to its inlet side, and closure, which means return to the original position, is only achieved from resultant tensile forces stored within the material of a moving part of the fluid valve.
- Thus, the number of moving parts required for the design of the fluid valve is reduced.
- A springless valve according to the invention can for instance be used to achieve a pressure build up within a cleaning device to a certain degree in order to utilize the pressure of the cleaning fluid for an extension movement of the nozzles. It is to be understood that the nozzle carrier according to the invention may be attached to a telescopic cylinder arrangement as well as to a pivot arm where the fluid pressure is used for shifting or rotating the pivot arm.
- The diaphragm type sealing member of the fluid valve is preferably made by a resilient material (for instance EPDM or rubber) designed such that it flexes away from its sealing position upon pressure built up. Upon pressure release the sealing member may flex back into its initial sealing position where it sealingly engages a valve seat which may for instance only be the peripheral rim of a fluid port.
- The sealing member comprises a cup-shaped diaphragm provided with a peripheral mounting flange, the diaphragm defining a substantially flat sealing surface yieldingly the engaging the sealing seat and being displaceable relative to the mounting flange upon the action of the fluid pressure.
- It is particularly advantageous when the sealing member yieldingly has a single piece design, the peripheral mounting flange and the cup-shaped diaphragm being connected via a circumferential relatively thin-walled web of resilient material.
- In one advantageous embodiment said distribution chamber comprises at least two cleaning fluid discharge openings each communicating with at least one spray nozzle.
- The invention is only clearly to be understood such that the distribution chamber may also comprise one inlet port and one discharge port. In this event the distribution chamber only serves as a housing for a diaphragm type sealing member.
- At least one spray nozzle, preferably all spray nozzles have an eye-ball design. "Eye-ball" design is a well-recognized term and describes a ball type nozzle body with a fluid discharge conduit extending therethrough, the discharge opening of the nozzle being designed as a circumferential cutout of the ball.
- Preferably the spray nozzles are snap-fitted into the nozzle carrier.
- One preferable embodiment of the device according to the invention is characterized by a retractable hollow cleaning liquid supply tube slidably arranged within an elongate housing connectable to a source of pressurized cleaning fluid and being biased in the retracted position, the nozzle carrier being attached to a distal end of the liquid cleaning supply tube.
- Of course this telescopic cylinder arrangement may comprise more than one cylinder, each cylinder being biased by a spring coil in the retracted position, in order to increase the amount of extension.
- One advantageous embodiment of the cleaning device according to the invention is explained hereinafter by way of example with reference to the accompanying drawings in which:
- Fig. 1
- shows a side-elevational view of the cleaning device according to the invention, partly cut in longitudinal direction,
- Fig. 2
- shows a top view of the nozzle carrier taken in the direction of the arrow II in
Fig. 1 , - Fig. 3
- shows a longitudinal section through the nozzle carrier taken along the line III-III in
Fig. 2 where the fluid valve is in its closed position and - Fig. 4
- shows a longitudinal section according to the one shown in
Fig. 3 where the fluid valve is in its closed position. - The cleaning device 1 according to the invention comprises an elongated
cylindrical housing 2 with a fluid supply 3 connectable to a source of pressurized cleaning fluid (not shown) and two retractable hollow cleaningliquid supply tubes housing 2. The fluid supply 3 is designed as a connector for receiving a hose fitted thereto. The hose in turn may be connected to an electrically operated cleaning liquid supply pump which is also not shown. - A cleaning device 1 as described hereinafter is designed as a headlamp cleaning device, however, the cleaning device may also be used a cleaning device for windshields or other vehicle surfaces to be cleaned.
- The cleaning device 1 may be mounted at the structure of a vehicle in concealed fashion, for instance within the bumper of a car.
- The cleaning
liquid supply tubes housing 2, the outside diameter of the first (leading)liquid supply tube 4a being smaller than the inside diameter of the cleaningliquid supply tube 4b, the outside diameter of the cleaningliquid supply tube 4a (trailing tube) being in turn smaller than the inside diameter of thecylindrical housing 2. -
Fig. 1 shows the telescopic cylinder arrangement formed by thehousing 2 and the cleaningliquid supply tubes cleaning supply tube 4a is guided within the cleaningliquid supply tube 4b at its trailing end (proximal end) by peripheral flange 5b, whereas cleaningliquid supply tube 4b in turn is guided withinhousing 2 by a peripheral flange 5b at its trailing end. At the same time the flanges 5a and 5b serve as a support for twocoil springs liquid supply tubes - At the leading end (distal end) of the inner
liquid supply tube 4a a nozzle carrier 7 is mounted. The nozzle carrier 7 is sealingly fitted on the leading end of the inner cleaningliquid supply tube 4a and in fluid communication therewith, the cleaningliquid supply tubes liquid conduit 8 for delivery of cleaning liquid the twospray nozzles 9 arranged at the distal end of the nozzle carrier 7. - The
spray nozzles 9 are designed as eye-ball type nozzles which are snap-fitted into receivingholes 10 of the nozzle carrier 7. The receivingholes 10 having a circular cross section, thespray nozzles 9 being arranged within the receivingholes 10 in an adjustable fashion. - As this can be seen from
Fig. 2 the receivingholes 10 and thus thespray nozzles 9 are arranged above a valve housing 11 (with reference to the position shown in the drawing). Thevalve housing 11 receives an elasticallydeformable sealing member 12 forming the bottom of a cleaningliquid distribution chamber 13. - The
valve housing 11 comprises a peripheral surroundingwall 14 which extends circularly. The sealingmember 12 is fitted into thevalve housing 11, which accordingly has a disk-shaped contour. - As mentioned before, the sealing
member 12 is made from a resilient material such as rubber, EPDM or the like and has a single-piece design. - As this can be taken from
Fig. 3 and4 the sealingmember 12 comprises a surroundingperipheral mounting flange 15 held in thevalve housing 11 by a cup-shapedcover 16 which is snap-fitted in a receivingopening 17 of the nozzle carrier 7, the space between the sealingmember 12 and thecover 16 is thereby defining acompensation volume 18 allowing displacement of the sealingmember 12, as will be explained in detail hereinafter. For this purpose thecompensation volume 18 is provided with aventilation hole 19, as this can be seen fromFig. 3 and4 . - The cleaning
liquid conduit 8 communicates via a circular andcentral inlet port 20 with thedistribution chamber 13. Thespray nozzles 9 are also connected to thedistribution chamber 13 viadischarge ports 21 which are disposed radially outwardly relative to theinlet port 20 when referring to the top view inFig. 2 . - Referring again to the design of the sealing
member 12, the sealing member has a central diaphragm type part which is cup-shaped in cross section and which forms acylindrical valve body 22. In the closed and non-pressurized condition of the cleaning device thevalve body 22, which forms a flat and disk-shaped sealing surface, sealingly engages aperipheral rim 23 of theinlet port 20. The circumferetial rim 23 of theinlet port 20 defines a valve seat for engagement with thevalve body 22. Due to the resilience of the material thevalve body 22 is yieldingly held in its closed position. Thevalve body 22 is connected to its surrounding mountingflange 15 via a circumferentialcorrugated web 24, the material of the web being remarkably thinner than the material in the area of thevalve body 22. - Once cleaning fluid under pressure is supplied, the pressure of the cleaning fluid causes displacement of the
valve body 22 to the direction of the arrow shown inFig. 4 . Thereby the cup-shaped part of the diaphragmtype sealing member 12 is flexed into thecompensation volume 18, i.e. downwardly inFig. 4 , thereby opening theinlet port 20 and thereby allowing ingress of cleaning fluid into thedistribution chamber 13. As thedistribution chamber 13 communicates viadischarge ports 21 with thespray nozzles 9, cleaning fluid is discharged onto the surface to be cleaned. - Upon ingress of the cleaning fluid via cleaning fluid supply 3 into the cleaning
liquid supply tubes valve body 22 is in its closed position as this is shown inFig. 3 . When the pressure of the cleaning fluid raises, first and inner cleaningfluid supply tube 4a will be extended against the force of coil spring 5a. Once the cleaningliquid supply tube 4a abuts cleaningsupply tube 4b the latter one also will make a forward extension movement until the second and outer cleaningliquid supply tube 4b abuts the leading end ofhousing 2. A further increase in static pressure acting on thevalve body 22 causes displacement, i.e. flexing movement of thevalve body 22 into thecompensation volume 18 thereby discharging the air trapped in thecompensation volume 18 viaventilation hole 19 and opening theinlet port 20. Upon pressure release thevalve body 22 will flex back into its initial position due to the tensile forces stored within the material of the sealingmember 11. - The design is simple to manufacture and has the least amount of moving parts.
